PHPMailer表单发送空字段值

这已经持续了一段时间,我似乎无法理解为什么。我已经构建了一个使用PHPMailer发送的表单,无论出于何种原因,我们不断从表单中获取带有所有空白字段值的电子邮件。这是在不同网站上的多种形式上发生的,都具有相同的设置。所以它不仅限于这种特定的形式。

将空白表单发送出去,表单在测试时可以正常工作。如果我填写并发送测试,一切都会好起来的。我不确定这些空提交是如何发生的。该表单使用javascript在大多数字段上进行验证。

这是我的HTML代码:

                    <div class="thank-you-message"></div>

                <form id="contactForm" class="form-horizontal" action="" method="post">


                    <!-- col 1 -->
                    <div class="form-l">

                    <div class="control-group">

                        <div class="controls">
                            <input type="text" name="first-name" id="first-name" class="validate[required,custom[onlyLetterSp],length[0,100]]" placeholder="first name" />
                        </div>

                    </div><!-- /.control-group -->

                    <div class="control-group">

                        <div class="controls">
                            <input type="text" name="last-name" id="last-name" class="validate[required,custom[onlyLetterSp],length[0,100]]" placeholder="last name" />
                        </div>

                    </div><!-- /.control-group -->

                    <div class="control-group">

                        <div class="controls">
                            <input type="text" name="email" id="email" class="validate[required,custom[email]]" placeholder="email address" />
                        </div>

                    </div><!-- /.control-group -->

                    <div class="control-group">

                        <div class="controls">
                            <input class="last" type="text" name="phone" id="phone" class="validate[required,custom[phone]]" placeholder="phone number" />
                        </div>

                    </div><!-- /.control-group -->

                    </div>
                    <!--../ col 1 -->
                    <!-- col 2 -->          
                    <div class="form-r">        

                    <div class="control-group">

                        <div class="controls">
                            <textarea rows="5" name="comments" id="comments" placeholder="message"></textarea>
                        </div>

                    </div><!-- /.control-group -->

                    <div class="control-group">

                        <div class="controls">
                            <button type="submit" class="submit"><span>send</span></button>
                        </div>

                    </div><!-- /.control-group -->
                    </div>
                    <!--../ col 1 -->

                </form>

这是phpMailer代码

正如评论中所述,很可能是垃圾邮件机器人,以及访问您网站但根本没有输入任何内容的人。这已知会发生。

我可以告诉你,你只是在检查if($visitorEmail == '')是否等于什么。

最好对表单字段使用条件语句,以及使用PHP

即:使用|| - OR运算符(如果其中一个为空)

if(!empty($_POST['form_field']) || !empty($_POST['other_form_field']))

   { 

// we are good to go, fire up your PHP/mailing code

}

else { 

   // do something else 

}

或(使用&& - AND运算符) - (如果一个不为空且已设置)

if(!empty($_POST['form_field']) && isset($_POST['form_field']))

   { 

// we are good to go, fire up your PHP/mailing code

}

else { 

   // do something else 

}

  • 将此逻辑应用于您的代码将有助于减少(如果不是消除空字段)。
